Enabling webcam on Fedora 20

Decided to try and be brave with grabbing a photo to upload to the address book.

dmesg was reporting the following error:

[ 12.101118] uvcvideo: Found UVC 1.00 device <unnamed> (05ca:1839)
[ 12.101567] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.
[ 12.101942] uvcvideo: Failed to query (129) UVC probe control : -32 (exp. 26).
[ 12.101945] uvcvideo: Failed to initialize the device (-5).

A quick G-search for ‘uvcvideo sony’ turned up, https://lists.ubuntu.com/archives/kernel-bugs/2010-July/128364.html, and after installing the libusb-devel.i686 and glib-devel.i686 (‘m on a 32-bit laptop) followed by,

r5u87x-loader --reload

does the trick. Installed cheese to grab the image from the webcam.

Note, however, that the following would probably have been a bit simpler,

# yum search uvcvideo
